[comp.graphics] Polyhedron from halfspaces

dean@CIS.OHIO-STATE.EDU (Andrew Dean) (11/14/89)

Hi.

Does anyone have C source code which takes as

INPUT: a collection of half spaces defined by inequalities

and returns as

OUTPUT: the faces of the convex polytope defined
        by the halfspaces?
	
(I want to draw the feasible region of 2D and 3D linear programs.)

Thanks for any help.
